My sister, brother, sister-in-law and myself are going on the NCL Viva in March. We are flying from Philadelphia to Puerto Rico. My sister and myself are both disabled senior citizens (mobility and visually impaired). We have airfare included through NCL. Going there is fine, we are all scheduled on the same flight but coming home we are on different flights, non-direct, leaving Puerto Rico and arriving back in Philadelphia at different times. Our travel agent says NCL refuses to change us all to the same flight. Is there anything that can be done?
